ACL Reconstruction Rehabilitation

ACL Reconstruction
Rehabilitation

Structured physiotherapy after ACL reconstruction surgery to restore knee movement, rebuild strength, improve control and safely progress toward everyday activity and sport.

Rehabilitation is individualized according to the surgical procedure, graft, associated injuries, surgeon's instructions, symptoms, strength and functional goals.

Why Rehabilitation Matters

Surgery repairs the ligament. Rehabilitation rebuilds function.

ACL reconstruction is performed to restore knee stability after an ACL injury, but the surgical procedure is only one part of recovery.

After surgery, the knee may have reduced movement, muscle weakness, altered balance and reduced confidence with loading. Physiotherapy addresses these limitations progressively.

The goal is not simply to make the knee feel better. Rehabilitation aims to restore strength, movement, neuromuscular control and functional capacity before higher-level activity is considered.

Rehabilitation Stages

Progress through recovery, one stage at a time.

Timelines vary between patients. Progression should be based on clinical findings and functional criteria, not time alone.

Early Rehabilitation

  • Control postoperative pain and swelling
  • Restore knee extension and appropriate mobility
  • Reactivate the quadriceps
  • Progress weight-bearing and walking as advised
  • Begin controlled strengthening

Progressive Rehabilitation

  • Build lower-limb strength
  • Improve balance and neuromuscular control
  • Progress functional movement
  • Develop running and jumping capacity when appropriate
  • Prepare for higher-level activity or sport
Physiotherapy Focus

What rehabilitation works on.

Exercise and activity are progressed according to healing, symptoms, strength, movement and functional performance.

01

Knee Mobility

Restoring appropriate knee range of motion, particularly extension, is an important early rehabilitation priority.

02

Quadriceps Strength

Progressive strengthening helps address postoperative muscle weakness and supports functional loading.

03

Balance & Control

Neuromuscular and balance exercises help improve control of the operated lower limb.

04

Functional Strength

Squatting, stepping and other functional patterns can be progressively trained as appropriate.

05

Running & Return to Sport

Higher-level activities should be introduced only when appropriate clinical and functional criteria have been achieved.

Recovery Journey

Progress, not pressure.

ACL recovery is not identical for everyone. Surgical details, associated injuries, strength, movement and rehabilitation progress can all influence the timeline.

EARLY

Protect & Restore

Early rehabilitation focuses on swelling, movement, muscle activation and safe mobility.

MIDDLE

Strength & Control

Progressive resistance, balance and functional exercises become increasingly important.

LATER

Return to Activity

Running, jumping, agility and sport-specific work may be introduced when clinically appropriate.

Return To Sport

Feeling better is not the same as being ready to return.

Return to running, jumping or competitive sport should be based on appropriate strength, movement quality, neuromuscular control and functional testing rather than simply reaching a particular number of weeks after surgery.

Important: Returning too quickly can expose the recovering knee to unnecessary risk. Your surgeon and physiotherapist should guide progression based on your individual recovery and surgical details.
